Response text

Based on this investigation, the following standard was selected and included in the work plan for review.

  • AS 7520.1 Body Structural Requirements – Locomotive

The updates focused on influencing future designs of primarily locomotives and passenger rolling stock by:

  • Specifically detailing requirements for rolling stock that is subjected to a rollover event.
  • Improving the survivability of train crew and passengers during and post an incident.

The updated standards were published in June 2025. https://www.rissb.com.au/products/as-7520-1-rolling-stock-body-structural-requirements-part-1-locomotive/

The key changes made to AS 7520.1 include the following:

  • Updated crashworthiness section to add requirements for rollover events and collisions
  • Amended reference standard for penetration resistance to align with current industry practice
  • Strengthened requirements for cab-mounted doors to minimise debris ingress during rollover events
  • Added requirements for windscreens to remain attached during emergency incidents
  • Added requirements for all glazing to meet standards for aerodynamic loads, pressure pulse tests, and passenger containment tests
